| 摘要： | A directly coating method,controlled double-jet precipitation(CDJP),was developed for synthesizing magnetic Fe3O4@Cu(OH)2 composites in combination of advantages of magnetic rapid separation and satisfactory adsorption performance.The morphology and structure of the composites were analyzedby SEM,TEM,XRD,FTIR,XPS and VSM techniques.Through controlling the reaction on Fe3O4 particles,directly coating of Cu(OH)2 was successfully realized without the extra complicated procedures.The obtained Fe3O4@Cu(OH)2 consists of micro particles of size around 250 nm coated with special leaf-like nanomorphologies,possessing high saturation magnetization(from 56.5 to 98.84 emu g-1).As the amount of loaded Cu is increased,As(Ⅲ)removal of the composites augments from 3.76 mg g-1 to 41.41 mg g-1.The Fe3O4@Cu(OH)2 composites is a hopeful candidate for treating arsenic contaminated water. |
